Hello there,
Actual price = $100
After 10% discount = $100 - (10/100 x 100)
= $90
After 15% discount = $90 - (15/100 x 90)
= $76.50
Final cost - $76.50
Hope this helps :))

What is your question that you want an answer to?
(not sure )
my method
let projection of b onto line dq be M
BM is 2r
then let the remaining angle ( right) be K
in triangle BMK ,
MK = 29-5-r
By Pyth. theorem ,
23^2 = (2r)^2+(29-5-r)^2
529=4r^2+576-48r+r^2
5r^2-48r+47=0
r = 8.493237063 or 1.106762937(rejected)
